I'm using a new Salifert Ammonia Test Kit; I find it hard to compare colors with the printed color test chart. Not too sure how accurately I (particularly the low range) interpret the comparison of colors. Is it just me, or is there a better kit available?
Thanks,
Id never spend that much on an ammonia test kit, its something you check a few times and not until the next tank, API is pretty cheap, nitrite to me is more truthful for testing
